<p>The Receive Data (QOLRECV) API performs an input operation on a link that is
|
||
|
|
currently enabled in the job in which the application program is running. The
|
||
|
|
type of data received is returned in the operation parameter. The data itself,
|
||
|
|
is returned in the input buffer that was created when the link was enabled. For
|
||
|
|
X'0001' operations, a description of that data is also be returned in the input
|
||
|
|
buffer descriptor that is created when the link was enabled.</p>
|
||
|
|
|
||
|
|
<p>The QOLRECV API can receive different types of data depending on the type of
|
||
|
|
communications line the link is using. See <a href="#HDRLANOPRR">LAN Input
|
||
|
|
Operations</a> for more information on the types of data that can be received
|
||
|
|
on links using a token-ring, Ethernet, wireless, or FDDI communications line.
|
||
|
|
See <a href="#HDRX25OPRR">X.25 SVC and PVC Input Operations</a> for more
|
||
|
|
information on the types of data that can be received on links using an X.25
|
||
|
|
communications line.</p>
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> The QOLRECV API should only be called when the
|
||
|
|
user-defined communications support has data available to be received. This is
|
||
|
|
indicated either by an incoming-data entry on the data queue or user queue, or
|
||
|
|
by the data available parameter on the QOLRECV API.</p>

<h3><a name="HDRLANOPRR">LAN Input Operations</a></h3>
|
||
|
|
|
||
|
|
<p>The only type of data that an application program can receive from the
|
||
|
|
QOLRECV API on links using a token-ring, Ethernet, wireless, or FDDI
|
||
|
|
communications line is user data (operation X'0001'). User-defined
|
||
|
|
communications support returns the following information for each data frame
|
||
|
|
received from the QOLRECV API:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>One or more data units. The first data unit contains a general LAN header,
|
||
|
|
routing information if a token ring is used, and user data.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>Total length of the data unit. This information is reported in the
|
||
|
|
corresponding input buffer descriptor element.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>For example, suppose two data frames came in from the network and the
|
||
|
|
user-defined communications application program was notified of this by an
|
||
|
|
incoming-data entry on the data queue or user queue. On return from the QOLRECV
|
||
|
|
API, the information for the first frame would be in the first data unit of the
|
||
|
|
input buffer and described in the first element of the input buffer descriptor.
|
||
|
|
The information for the second frame would be in the second data unit of the
|
||
|
|
input buffer and described in the second element of the input buffer
|
||
|
|
descriptor. The number of data units parameter would be set to 2.</p>
|
||
|
|
|
||
|
|
<p><strong>Data Unit Format-LAN Operation X'0001'</strong></p>
|
||
|
|
|
||
|
|
<p>Each data frame received from the QOLRECV API corresponds to a data unit in
|
||
|
|
the input buffer. The information in each of these data units is made up of a
|
||
|
|
general LAN header, routing information (for token-ring links only), followed
|
||
|
|
by user data.</p>
|
||
|
|
|
||
|
|
<p>The general LAN header is used to pass information about the frame to the
|
||
|
|
communications support. The fields in the general LAN header are used for all
|
||
|
|
LAN link types, although some of them are link specific. For example, routing
|
||
|
|
information is only for token-ring links, and the length of routing information
|
||
|
|
is X'00' to X'18'. For non-token-ring links, the length of the routing
|
||
|
|
information is always X'00'. Also, DSAP and SSAP are defined for protocols that
|
||
|
|
use the 802.2 logical link control interface and do not apply to Ethernet
|
||
|
|
Version 2. A DSAP and SSAP of X'00' tells the communications support that the
|
||
|
|
data frame is an Ethernet Version 2 frame.</p>

described in the first element of the input buffer descriptor. The second
